Wooden window sash



Patented Nov. 3, 1942 UNITED STATES rar OFFICE This invention relates towindow sash, and more particularly to wooden window sash of large sizesuch as used in industrial buildings, schools, and the like. A

In my Patent No. 2,201,577 a window sash is disclosed that is of thesame general form and for the same general purpose as the sash to bedisclosed herein. However, my patented sash is made of metal which thewar has made very dicult to obtain for such purposes, and is constructedin a way that is not suitable for wooden sash. I have therefore inventeda window sash of the same general character whichis made of wood andwhich can be shipped in the knockdown and readily lassembled inunlimited sizes at the building site as the case with my metal window. l

It is among `the objects of this invention to provide a window sash ofwood which is adapted to be fabricated as it is being installed in thewindow opening of a building, which can be read-v ily formed in anydesired size, which can be quickly and easily assembled, which is strongand durable, which is relatively inexpensive to make and install, inwhich the glass can be quickly in stalled, and in which the metalmembers that fasten the vertical and horizontal members vtogether areprotected from the weather.

In accordance with this invention a window sash adapted to ll a windowopening of any desired size is fabricated of wooden members in theopening itself as it is being installed therein. That is, a plurality ofvertical mullions rst are connected at their ends to the top and bottommembers framing the window opening, a suii-v cient number ofmullionsbeing used to give the desired spaces between them for panes of glass4throughout the width of the window. A plurality of vertically spacedhorizontal members are then form rectangular glass-receiving openings.To position the horizontal members the front portions of the mullionsare provided with transverse notches that receive the horizontal memberswhich are held in place in any suitable manner. It is preferred to slopethe top and bottom walls of the notches downwardly from thefront facesof the mullions and to likewise slope the top and bottom surfaces of thehorizontalmembers downwardly toward their rear surfaces so that theywill fit into the notches. Screws or other fastening members can then beinserted between the top walls of each horizontal member and notch withthe screw threads embedded in the member and adjoining mullion'forlocking the horizontal 55 fastened to the front of'v the verticalmullions to; 40

vided with longitudinal channels for receiving thel top and bottom edgesof panes of glass the ends of which overlap the "vertical mullions andythe screws that hold the horizontal members in place. Each mullionpreferably is provided along the central portion of its front surfacewith an integral vertical rib projecting between the ends of the panesof glass on both sides of it. y

- The preferred embodiment of the invention is illustrated in theaccompanying drawing in which Fig. 1 is a fragmentary front view of mywindow sash installed in the wall of a building; Fig. 2 is an enlargedvertical section taken on the broken line II-II of Fig. l; and Fig. 3 isan enlarged horizontal section taken on the broken line III--III of Fig.1'.

Referring to the drawing, the wall i of a building is provided with awindow opening 'of any desired size. Extending along the top of theopening is a horizontal framing member 2 that engages a vertical framingmember 3 at each end. Extending along the bottom of the opening is asill 4 on which a horizontal framing member Y5 rests. All of thesemembers are made of wood and are joined together in any suitable manner.

It is a feature of this invention that the wooden .operation and theircost thereby reduced. The

first step is to individually and directly connect the ends of aplurality Iof separate vertical mullions 1 to the upper and lowerframingmembers 2 and 5 in the window opening by any suitable means.

entirewidth of the opening with the end framing members 3 serving as theend mullions of the window. A plurality of separate horizontal membersor bars 8 are then individually connected to the front of the verticalmullions at vertically spaced intervals in a manner to be describedpresently. The number of bars used will depend, of course, upon thedesired height of the glass-receiving openings and the heightof thewindow. The bars extend the full width of the window, being disposed endto end with their joints overlapping the mullions when the window is toowide for a bar of convenient length.

TheV horizontal bars lare formed vto facilitate t simple andrapid-installation of the panes of glass* These mullions are disposed atprede-M termined horizontally spaced intervals across the 9 without theuse of separate fastening members. For this purpose each of the barspreferably is provided with upper and lower channels Il and l2 (Fig. 2)the lower one of which is deeper than the upper one so that the upperedge of a pane of glass can be inserted in the lower channel of a bar,raised therein until its lower edge clears the top of the bar below it,and then lowered into the shallow upper channel of the lower bar withthe upper edge of the glass still retained in the deeper bottom channelof the upper bar.

To position the horizontal bars 8 and hold them parallel, the verticalmullions, including the enl framing members 3, are provided in theirfront portions with vertically spaced transverse notches I 4 in whichthe bars are mounted, as shown in Fig. 2. 'I'he notches are of suchdepth that the rear walls of glass-receiving channels Il and I2 arelocated substantially flush with the front surfaces of the mullions sothat the ends of the glass panes overlap the mullions in close proximitythereto. To line up the panes of glass and to improve the appearance ofthe window each of the vertical mullions is provided along the center ofits front surface with a vertical rib I5 integral therewith. This ribprojects between the ends of the adjacent panes of glass, but not anappreciable distance beyond their outer surfaces.

The horizontal bars are securely retained in the mullions in a Simplebut effective manner by sloping the top and bottom walls of notches I 4downwardly from the front of the mullions and by similarly sloping thetop and bottom surfaces of bars 8 downwardly from their channels Il andl2 toward their rear sides. Fastening members inserted between the topwalls of the bars and notches prevent the bars from tipping out of thenotches, while the bottoms of the bars are locked in the notches by theinclination of their bottom walls. Preferably, screws I6 (Fig. 2) areused as the fastening members with their threads embedded in theadjoining upper surfaces of the bars and notches. The heads of thescrews are forced into the wooden mullions far enough to prevent themfrom interfering with setting of the glass in the channels, and are thusprotected from the weather by the glass so that steel screws can be usedrather than brass which is now difficult to obtain for such purposes.

The upper portion of the window shown in the drawing is provided with ahinged section for Ventilating purposes, and the lower portion of thewindow may be provided with la similar ventilator if desired. The hingedsection comprises a wooden frame .2| hinged at its top to the bottom ofthe upper horizontal member of the window so that the bottom of theframe can be swung out. This frame is divided into glass-receivingsections by short vertical members 22 in front of mullions 'l and theupper portions of which are cut away to receive these members. Each ofthese vertical members has an integral -rib 23 along the center of itsfront projecting between the ends of the adjoining panes of glass. Asshown in Fig. 3, these ribs project farther than those on the mullionsin order to strengthen the hinged frame. Directly behind each end of thehinged ventilator is a small rectangular frame 24 mounted in fixedposition and provided with a pane of glass 25 for intercepting rain thatmay blow in past the end of the open ventilator.

The ends of the window are iinished by mounting a vertical facing strip21 against the front. of` each of the end members 3. The rear side ofeach facing strip is notched to receive and enclose the portions ofhorizontal bars 8 projecting from the vertical end members.

With a window sash constructed in accordance with this invention thewindow frame and the sash frame are combined into one with the resultingeconomies. There is no factory fabrication of the sash, and it ischeaper to handle before installation because it can be shipped andhandled in knock-down condition. The method of assembly is simple andrapid. Windows of any desired size can be furnished with a single sash,whereby the cost of making several sash and connecting them together ina single window opening is avoided.

According to the provisions of the patent statutes, I have explained theprinciple and construction of my invention and have illustrated anddescribed what I now consider to represent its best embodiment. However,I desire to have it understood that, within the scope of the appendedclaims, the invention may be practiced otherwise than as specificallyillustrated and described.
